PETA's dirty little secret

I don't have a particular interest in the debate over PETA's position. (For the record, I believe killing an animal does not carry the same weight as killing a person, but it should be done humanely whenever possible.) However, this site seems to have some rather negative things to say about PETA which, if true, call into questions the true motives of the group.

From July 1998 through the end of 2003, PETA killed over 10,000 dogs, cats, and other "companion animals" -- at its Norfolk, Virginia headquarters. That's more than five defenseless animals every day. Not counting the dogs and cats PETA spayed and neutered, the group put to death over 85 percent of the animals it took in during 2003 alone. ... On its 2002 federal income-tax return, PETA claimed a $9,370 write-off for a giant walk-in freezer, the kind most people use as a meat locker or for ice-cream storage. But animal-rights activists don't eat meat or dairy foods. So far, the group hasn't confirmed the obvious -- that it's using the appliance to store the bodies of its victims. In 2000, when the Associated Press first noted PETA's Kervorkian-esque tendencies, PETA president Ingrid Newkirk complained that actually taking care of animals costs more than killing them. "We could become a no-kill shelter immediately," she admitted.

I had heard from other sources that PETA's true agenda is total animal liberation - no zoos, no circuses, no house pets and no fences. Not sure how this fits into that argument - anybody heard anything related?
